Detecting Cooperativity between Transcription Factors Based on Functional Coherence and Similarity of Their Target Gene Sets. [PDF]

open access: yesPLoS ONE, 2016
In eukaryotic cells, transcriptional regulation of gene expression is usually achieved by cooperative transcription factors (TFs). Therefore, knowing cooperative TFs is the first step toward uncovering the molecular mechanisms of gene expression ...

Feature selection for microarray gene expression data using simulated annealing guided by the multivariate joint entropy [PDF]

open access: yes, 2013
In this work a new way to calculate the multivariate joint entropy is presented. This measure is the basis for a fast information-theoretic based evaluation of gene relevance in a Microarray Gene Expression data context.

Synstable Fusion: A Network-Based Algorithm for Estimating Driver Genes in Fusion Structures

open access: yesMolecules, 2018
Gene fusion structure is a class of common somatic mutational events in cancer genomes, which are often formed by chromosomal mutations. Identifying the driver gene(s) in a fusion structure is important for many downstream analyses and it contributes to ...

Comparison of five supervised feature selection algorithms leading to top features and gene signatures from multi-omics data in cancer

open access: yesBMC Bioinformatics, 2022
Background As many complex omics data have been generated during the last two decades, dimensionality reduction problem has been a challenging issue in better mining such data. The omics data typically consists of many features. Accordingly, many feature

Methods for evaluating clustering algorithms for gene expression data using a reference set of functional classes [PDF]

open access: yesBMC Bioinformatics, 2006
A cluster analysis is the most commonly performed procedure (often regarded as a first step) on a set of gene expression profiles. In most cases, a post hoc analysis is done to see if the genes in the same clusters can be functionally correlated. While past successes of such analyses have often been reported in a number of microarray studies (most of ...

Inferring causal relations from multivariate time series : a fast method for large-scale gene expression data [PDF]

open access: yes, 2009
Various multivariate time series analysis techniques have been developed with the aim of inferring causal relations between time series. Previously, these techniques have proved their effectiveness on economic and neurophysiological data, which normally ...
